nrrs STATES PArENToFsicE GORDON WILLIAM FREDERICK CATLIN, OF ST. ENGLAND APPARATUS FOR SEPARATING FAT OR OTHER MATERIAL FROM Application filed January 8, 1929, Serial No. 331,131, and in Great Britain February 3, 1928.

This invention relates to apparatus for separating fat or other material from gases and has reference more especially to an arrangement and device whereby molten fat in a finely divided state of suspension in air may be readily separated therefrom without unduly affecting the normal functioning of the apparatus.

Broadly the present invention resides in an improved form of apparatus for attaining the object referred to and according to which a mixture of finely divided fat or other material and a gas such as air isdrawn off laterally from the chamber in which the 1 mixture is formed, said mixture being then adapted to encounter one or a series of baffie devices serving to retain all or a considerable quantity of the relatively solid material while the gas is further adapted to pass through a suitable outlet port or its equiva lent arranged in such a manner that by the time the gas has arrived at said delivery portion of the apparatus all or the desired amount of solid material has been retained within the apparatus and the gas may be allowed to escape or be subjected to further treatment.

In the accompanying drawings Figure 1 illustrates in part sectional side elevation one convenient form of apparatus by means of which molten fat may be separated from air in accordance with the invention, while Figure 2 is a sectional side elevation or" the apparatus shown by Figure 1,

Referring now to these drawings the numerals 2 and 3 designate respectively two oppositely'disposed and laterally extending ducts adapted to emerge from respectively opposite sides of a chamber 4: which forms a housing for the fat and air mixture which latter is formed for instance in the case where one or a series of .fat spraying nozzles 5 arev employed for the treatment or dressing of sponge cake tins preparatory to the baking process. The housing l according to the example illustrated encloses the jet portions of the nozzles while the articles to be treated with fat may be adapted to. pass through an opening 6 in a portion of the apparatus 59 connecting the mixing chamber 4; to an a-ux-' iliary chamber 7 located belowthe mixing,

chamber 4. The. opening 6 also forms a gas lnlet to the chamber 4-. The ducts 2 and 3 are adapted to bend and communicate with the auxiliary chamber 7 located immediately below the mixture chamber l'said auxiliary chamber being provided with a number of bailie elements 8' consisting for instance of plates disposedin' such relation that, the mix: ture is caused to. assumea tortuous passage when being drawn through the auxiliary chamberand as shown by the arrows in Figure 1. During the passage of the mixture through the separating chamber, fat is deposited upon the baftle plates 8 and in-the present examplethe entire auxiliary chamher 7 is water-jacketed as shown at 9, the water being kept at a temperature suficient to maintain the fat in a molten condition. By this means the fat deposited" within the separating chamber 7 is adapted to collect at the bottom thereof and a drain-01f cock 10 is providedfor enabling theapparatus to be cleaned from time to time.

Anysuitable form of extracting tan or device may be employed for drawing oft" theair ill from the apparatus there being provided an exhaust port, 10?) arranged near the upper portion-of the auxiliary chamber-7 and located at one of the sides of the same but conveniently remote from the entry portion for the lateral and downwardly depending ducts 2 and 3communicatingwith the upper chain her 4: within which the mixture is formed initially. Any fat, or material which is not drawn through into the auxiliary chamber may be adapted to fall directly upon a collecting plate 11 shaped or disposed so that the said fat or material may travel through a port onjdelivery opening lQ; communicating dl'.

rectly with theauxiliary chamber 7.

The auxiliary chamber 7 may be fitted to .the remainder of the apparatus in any desired manner and the system of water jacketting employed may of course be replaced by any other equivalent form of device for preserving the requisite high temperature within the auxiliary chamber.

In the case wherea device of the foregoing description is employed for separating oils lOO or materials which remain fluid at ordinary temperaturesthe use of a water jacket forthe j r V auxiliary chamber may be dispensed with.

What I claim and desire to secure by Let- 'tersPatentis: s 7 7 1. Apparatus for separating fat from gases, comprising a mixing chamber, spray nozzles for admitting fat to the mixing chamher, a gas inlet to the mixing chamber, two
